The SWAT team and hostage negotiators were called in and mutual aid responded as backup to New Haven Police. Officers soon established communication by phone with Tennant. Police said he requested help and agreed to come out peacefully.

Police said, "though a peaceful resolution to the barricaded person incident was achieved, the on-going investigation has revealed a disturbing pattern of domestic abuse at the hands of Tennant."

“There is no special treatment of officers by this department when it comes to the commission of a crime," said Chief Anthony Campbell. “We have an obligation to the victims, an obligation to uphold the law and assure that the perpetrators of crimes are held accountable," said Campbell.

Tennant is suspended from the department, pending the outcome of the case, according to police.
